"Morton holds up insider movement advocacy (IMA) alongside biblical content and a sound way of reading the Bible. In example after example, Morton shows that biblical texts do not say what IMA uses them to say . . . He highlights the necessity of a solid biblical theology of religions. And he does it all in a chatty, personal style that includes touches of humor. It is extremely rare to find such an even, sensible, and friendly treatment of the IMA controversy, completely free of animus and grudge."
—Gordon Nickel, author of Narratives of Tampering in the Earliest Commentaries on the Qur'an

"If anybody wants to get an analysis of insider movements from a biblical perspective, this is a good book to start with. But be prepared to be shocked once in a while."
—Eddy Lanz, Forum Wiedenest

"Morton aims a laser beam of clarity through the fog of insider movement (IM) theology, shining a corrective beacon upon common IM interpretations of key biblical passages and illumining certain assumptions that grip IM proponents. Through Scripture and around the world in just over one hundred pages, you will discover surprising and disturbing features of IM thinking, but you will also—by the careful, balanced, and biblical way in which Morton responds—find your heart burning afresh for the faithful preaching of the gospel . . . This is a must-read for those who love Christ and are concerned that Christ's name is proclaimed faithfully."
—David Garner, Associate Professor of Systematic Theology, Westminster Theological Seminary

"This is a simple book with a simple theme: insider movements are not biblical."
—Elijah Abraham, Founder and Director of Living Oasis Ministries

"Morton has exposed the real Achilles heel of insider movements. This book helps us see the problems of claiming biblical support for a movement advocated by many ill-trained Western missionaries."
—Joshua Lingel, Founder of i2 Ministries

"Morton has taken a topic saturated with missiological gobbledygook and made it as clear as a pane of glass. If you need clear, biblical reasons why insider movements are a giant step in the wrong direction, read this book."
—Bill Nikides, teaching elder in the Presbyterian Church in America

"Whether it is a biblical blueprint for fulfilling the great commission or merely a Trojan horse for heresy, it is high time for the insider movement to be taken seriously. In this fascinating book, Morton does exactly that by unpacking and critiquing the movement's claims to biblical authority. This gracious but unapologetic turn in a conversation about biblical truth is also a call to the church to stop looking the other way, join in the conversation, and come to an informed decision."
—Mark Durie, human rights activist and Anglican pastor
